In the future, the Blood Plague has crippled society and the Doctors now rule. Ren Grant’s parents were killed by the Doctors and she has been on the run since as a Carrier of the Plague. When Ren is finally found, it is not by the Doctors, but by Rian Sloan and his group who are looking for a Keeper’s Watch. Ren happens to have her mother’s Watch. Rian needs her Watch to board a ship and escape Earth. Ren travels with Rian and his group to Myrreka. Ren goes through an adventure that will take her through danger, friendship and new trials.​Ren really captured me from the beginning of this story. Her situation and mode of survival made Ren interesting and easy to care about. I was intrigued by her backstory, her mother’s secret and the mystery of the Watch. It was fascinating to see what had happened to other cities after the Blood Plague as the group travelled. Ren grew as she found her dynamic within the group and learned more about her past and how to defend herself. For me, some of the travelling sections dragged a little for me. The story picked up again for me as Ren’s Watch began to show its potential. The ending threw me for a huge loop and ended on a bit of a cliffhanger, so I am really interested in the next book.
